Oriental Herbal Nutrient (OHN) KNF Input, Herbal Plant Tonic for Vigor & Resilience, 8 oz Makes 48 Gallons

🌿 Oriental Herbal Nutrient (OHN), Made on Our Farm

Oriental herbal nutrient, known across Korean Natural Farming as OHN, is the botanical tonic of the system. We extract a blend of warming, aromatic herbs, garlic, ginger, angelica root, licorice, and cinnamon, into spirits to draw out their plant-supporting compounds, then deliver them in a form your plants take up through leaf or root. It is a cornerstone KNF preparation valued for supporting plant vigor and resilience.

OHN is not tied to one growth stage like the fermented juices. It is the steady, season-long tonic in the routine, applied as a foliar spray or soil drench to help plants stay vigorous and resilient through the demands of a full season, in heat, in crowding, and through every hard stretch. For how it fits alongside the other inputs across the calendar, see our master guide to KNF inputs.

We make this on our own farm in Colorado, and it is part of the input regimen that helped our soil reach a Haney Soil Health Score of 25.4, a number that surpasses the soil biology measured in pristine forest land. We farm soil-first because we believe healthier, more biologically alive soil grows stronger, more resilient plants, and our herbal tonic is part of how we keep them that way.

One 8 oz bottle goes a long way: at one teaspoon per gallon it makes 48 gallons of finished tonic. Curious about the herbs and the tradition behind the blend? Read more on our See the Science page.

🌼 Frequently Asked Questions

What is Oriental Herbal Nutrient and what does it do?

OHN is the herbal tonic of Korean Natural Farming. We extract garlic, ginger, angelica root, licorice, and cinnamon into spirits, and that blend is valued for supporting plant vigor and resilience. We use it as a regular tonic in our routine to help our plants stay strong and thriving through the season.

---

When in the season should I use OHN?

Unlike the fermented juices that target one growth stage, OHN is a steady tonic we apply right through the growing season. We lean on it especially when plants are working hard, in heat, in crowding, or through a demanding stretch, to support their natural vigor and resilience.

---

Can I just make my own OHN?

You can, and we love that Korean Natural Farming is built to be shared. What you get from us is the exact herbal nutrient we make on our own farm in Colorado, the same one that helped build soil with a Haney Soil Health Score of 25.4. It comes as a ready, blended extract you dose at one teaspoon per gallon, so you can skip sourcing five herbs and the weeks of extraction and put it straight to work.

---

How do I dilute it, and how far does one bottle go?

Mix one teaspoon into one gallon of water, which is about a 1:750 dilution. At that rate the 8 oz bottle makes 48 gallons of finished tonic. Apply it as a light foliar mist or a soil drench in the early morning or evening, and you can combine it with other KNF inputs in the same routine.
